Tree 10-25 m. Twigs 2-6(-8) mm diameter, rather early glabrescent, hairs yellow-brown or rusty, woolly, 0.2-0.5 mm; bark coarsely striate, not flaking; lenticels sparse to dense, distinct or not. Leaves coriaceous, elliptic to oblong, 10-20(-28) by 3.5-7(-10) cm, base rounded to attenuate, apex rounded to subacute or rarely emarginate; upper surface drying dull greenish brown to dark brown, lower surface ± covered with sub-persistent interwoven or spaced stellate scale-like hairs 0.1 mm high (when very young with dendroid emergents), or glabrescent and then showing distinct hair scars, and scattered dots and dashes; midrib above flattish; nerves 11-16 pairs, above thin and flat or sunken; venation faint on both surfaces; petiole 9-20(-30) by 1.5-4.5 mm, leaf bud 7-12 by 2-3 mm with hairs 0.2-0.5 mm. Inflorescences among or behind the leaves, late glabrescent or with persistent, dense, woolly dendroid hairs 0.2-0.5 mm; in male: 3-5 times branched, broadly paniculate, many-flowered, 6-20 by 4-15 cm, peduncle 0.5-2 cm long; in female: 3-14 cm long; bracts elliptic-lanceolate, 2-5(-7) mm long, pubescent, caducous; flowers (male) in loose clusters of 2-7, glabrous; perianth 2-lobed, pedicel slender, not articulated. Male flowers: pedicel (0.3-)l mm long; buds globose or slightly transversely ellipsoid, (0.8-)l-1.3 by 1-1.5 mm, cleft l/3-l/2(-2/3), lobes 0.2-0.3 mm thick; androecium globose or ± transversely ellipsoid, barely laterally compressed, 0.4-0.5 by 0.5-0.8 mm (Plate 2: 60); thecae (6-)8-12, widely spaced, connectives broad (and androecium angular), the anthers free for almost the upper half or more; androphore 0.2(-0.3) mm long, slender. Female flowers: pedicel 1.5-2.5 mm long; buds broadly obovoid, 2-3 by 2-2.5 mm, cleft 1/5-1/3, lobes 0.6-1 mm thick; ovary obovoid, glabrous, 1.5 by 1.2-1.5 mm, stigma of 2 sessile small lobes 0.1-0.2 mm high, running out into a faint ridge at one side of the ovary. Fruits (1—)2—10 per infructescence, ovoid to obovoid, 1.5-2.2 by 1.2-1.8 cm, glabrous, drying dark brown, with at most few lenticel-like tubercles; pericarp 1.5-2 mm thick; fruiting pedicel 2-5(-7) mm long; perianth persistent.
